Description
Element BioThane® Long Line
Extended Training Leash, Built for Real-World Use
The Element BioThane Long Line is where Bolder K9 began. Originally made for fosters and adopters at True North GSD Rescue, this leash was designed with a simple goal: maximum function, zero fluff. It’s a tried-and-true long line built for training, decompression walks, recalls, and muddy Pacific Northwest conditions.
Dependable, strong, and easy to maintain, the Element Long Line is designed to handle everything from structured training sessions to everyday outdoor adventures.
Beyond the Donation
Every Bolder K9 purchase supports our Beyond the Donation program, where we go beyond traditional giving by combining financial support with hands-on volunteer work for dogs and their people.

Frequently Asked Questions
Everything you need to know about our handmade BioThane® gear, production timelines, shipping, care, sizing, and custom orders.
How do I care for my BioThane® gear? +
BioThane® is waterproof, odor-resistant, and easy to maintain. Most dirt wipes off with warm water and mild soap. For heavier messes, soak in diluted oxiclean (unscented), then rinse and dry thoroughly. We recommend avoiding prolonged exposure to strong DEET-based insect repellents, which may affect the coating over time.
What if my dog chews through an item? +
Our gear is designed for durability, but no product is chew-proof. Damage caused by chewing is not covered under warranty. If something happens unexpectedly, reach out — we’re always happy to review the situation and see what options may be available.
What is considered normal wear and tear? +
Normal wear includes cosmetic signs of use such as minor scuffs, scratches, fading, or coating wear on hardware over time. Black hardware may naturally show silver underneath with regular use — this is expected and cosmetic only. Wear from chewing, misuse, improper storage, or unsafe restraint is not covered.
How much is shipping and how long will my order take? +
Our production time for most orders is 2-3 weeks unless otherwise specified. Once shipped, delivery typically takes 1–5 business days depending on location. Shipping rates are calculated at checkout, with free shipping available on orders over $75. Need it sooner? We also offer expedited processing options when available.
How are your products packaged? +
Orders are packaged simply and intentionally to protect your gear while minimizing waste. We focus on practical packaging that gets your order safely to you — nothing excessive.
Do you offer returns or exchanges? +
Because most items are handmade to order, we generally do not accept returns on custom gear. If there is a sizing issue, please contact us — we’ll always do our best to help find a solution. If there is an issue with workmanship or a mistake on our end, we’ll make it right.
Can I cancel my order? +
Orders may be canceled within 24 hours of purchase. After that, production may already be underway and cancellations are no longer guaranteed.
Do you offer wholesale pricing? +
Yes. We work with select retailers, trainers, and partners who align with our brand and values. Contact us for more information about wholesale opportunities.
How do I choose the right size? +
Visit our sizing guide page to learn more about sizing. If you’re between sizes or unsure, reach out before ordering — we’re happy to help you choose the best fit for your dog.
Can BioThane® get wet? +
Yes — BioThane® is fully waterproof and made for muddy trails, rainy walks, dock diving, and everyday adventure. It won’t absorb water, hold odor, or stay soggy like traditional materials.
